This series adds support for USB phy tuning parameters, which are
required for meeting USB certification and EMI qualification.
Patch 1/2 adds the required properties to the fsl,imx8mq-usb-phy
devicetree binding.
Patch 2/2 adds the phy tuning parameters to the phy-fsl-imx8mp driver.
This patch is ported and cleaned up from the downstream Freescale vendor
tree.
Best regards,
Johannes

Changelog:
v1 -> v2: worked in review from Krzysztof and Rob, thanks for your
review:
- extract more useful descriptions of the properties from the
datasheet
- use unit postfixes for the device tree properties to facilitate
porting in the future
- add more information about some of the properties (thanks to Li Jun
for clarification)
- adjust parsing of the devicetree properties in the driver to scale
to the proper register values
